And the environmental benefits continue even afterthe UCG process delivers synthesis gas to the surface.UCG synthesis gas, when used for gas turbinecombined cycle power generation, provides about a 25per cent4reduction in greenhouse gas emissions, orover a 60 per cent reduction when used with carboncapture when sequestering the carbon dioxide backinto the UCG cavity for storage.UCG synthesis gas used to produce synthetic dieselalso has similar environmental benefits. Linc Energy'sUCG to GTL Chinchilla Demonstration Facility hasproven that a tonne of deep coal can be converted intocleaner diesel at about US$28 per barrel. It is theunique GTL fuel production process that can producediesel and jet fuel with lower emissions.Australia's Commonwealth Scientific and IndustrialResearch Organisation (CSIRO) compared transportfuels in a recent report to the Australian GreenhouseOffice. Diesel produced from UCG synthesis gas wasdeemed to have reduced tailpipe emissions. UCGdiesel was found to contain zero sulphur, 19 per centless carbon monoxide, 35 per cent less fine particulates(PM-10), and 43 per cent less hydrocarbon gases5.What is more impressive with diesel produced fromUCG synthesis gas is that it is considered superiorcompared with conventional diesel. It has near zeroaromatics, and a high cetane number providingexcellent combustion properties. It is the premium fuelfor diesel engines.The case for UCG and extracting energy from coal in aneconomically and more environmentally friendly waygets better as more research is conducted on returningproduced carbon dioxide from the process to theexhausted UCG cavity in a safe manner. A form ofcarbon capture and storage (CCS), the sequestration ofcarbon dioxide into previously used UCG cavities isgaining momentum.CLEAN COAL TECHNOLOGY027Above: Linc Energy CEOPeter Bond sees agreener future in cleanercoal technologyBelow: UCG synthesis gasis an ideal feedstock forthe GTL process toproduce cleaner dieseland jet fuelBIOGRAPHYPeter Bond is Chief Executive Officer of Linc EnergyLtd. He began his career in mining thirty years ago,after training as a metallurgist at BHP. At the age of 23,his entrepreneurial streak shone and he personallyraked and hand cleaned over 1,000 tonnes of coal,which he sold to a brick company for AU$17,000. Afteryears in the coal industry, Mr Bond went on to own hisown coal company. Since then he has been involved intransforming underperforming companies into valuableassets, in both Australia and overseas. From late 2004,and in just three years, Bond has transformed LincEnergy from a small start-up, to a successful IPO on theAustralian Securities Exchange (ASX) - and ontobecoming an AU$2 billion ASX200 company. Mr Bondis also a member of the BRW Australian Rich List and is known for his philanthropic efforts.There are a number of studies underway in Germanyand the United Kingdom on the combined use of UCGand CCS for a cleaner world. The UCG Partnership,based in the United Kingdom, says UCG combinedwith CCS is a potential route to carbon abatement from coal6. If governments and world climate bodiesseek reductions in greenhouse gas emissions, then technologies that offer cleaner solutions need tobe supported.The UCG cavity is more than capable of absorbingcarbon dioxide. After UCG, the remaining carbon in the coal seam is more permeable, enabling the cavity to store up to two thousand times more carbon than traditional means of CCS. UCG combinedwith CCS suggests the process can be carbon neutral. Linc Energy is developing a UCG and CCS program.If technologies like UCG and CCS reach thecommercial platform they deserve, coal-rich nations,amid the discussions on reducing emissions, areensured economic stability and energy security for theforeseeable future. With US$28 per barrel clean fuelavailable from coal, UCG has to be seen as the energyalternative of the future. n1 Coal Chapter, Survey of Energy Resources 2007,World Energy Council.2 BP Statistical Review of World Energy, 2006.3 Underground Coal Gasification Chapter, Survey ofEnergy Resources 2007, World Energy Council.4 Compared with the most efficient, supercritical,pulverised, Australian, coal-fired power stations usingmined coal.

" "o meet the global challenges facing ustoday, we need to create a stronger,more effective international framework.The critical importance of concertedmultilateral action was at the heart of the COP15climate summit last December in Copenhagen.A lot was at stake - and still is. That is why weworked so hard in Copenhagen to achieve a globalagreement. And this is why the outcome of COP15 -the Copenhagen Accord - is so important.125 heads of state and government convened inCopenhagen to start building a new global frameworkto combat climate change. The Copenhagen Accordis a major achievement in this regard. Many leadersplayed a decisive role in brokering the agreementand I would like to take this opportunity to thank allof them for continued support to the CopenhagenAccord. This agreement provides the fundamentals of aglobal framework and reconfirms the principlesestablished by the United Nations FrameworkConvention. It sets out the target to limit globalwarming to below 2°C and creates a critical linkbetween this goal, the international cooperation toachieve it, and the contributions of individualcountries. The Accord also includes important elements relatedto technology development and transfer as well asfinancing, which will assist developing countries inimplementing mitigation actions. The decision to establish a Technology Mechanism will helpcountries in moving towards low-carbon societies.More than 120 countries have by now associatedthemselves with the Copenhagen Accord. Thisincludes all the major economies. The countriesrepresent 90 per cent of the world's GDP and 83 percent of global emissions. We shall build on this tofurther strengthen international cooperation aimingto address global warming and create further low-carbon growth. Much of the transition will take place in the nationaleconomies and within the economic planning ofindividual countries. National governments have a key role in creating incentives and establishing the right regulatory framework for markets andcompanies to undertake green investments.Denmark may be a small country but when it comesto energy efficiency and cleantech, we offer valuableexperience and technologies. As many countriesembark upon realising their ambitious targets toensure sustainable growth, we may benefit mutuallyfrom an even closer cooperation in clean technology.It is my clear impression that these countries are notgoing to repeat what some industrialised countriesdid: grow now, clean up later.The first movers of today are the winners oftomorrow. And so are the fast movers. On cleantechnology, Denmark is a first mover and manycountries are now fast movers. If we join forces and engage in close cooperation all our nations will benefit. Globally, we will see a massive increase in greeninvestments in the years to come. There has alreadybeen a huge increase, but more is needed. It isestimated that we will have to make additionalinvestments of more than US$10 trillion in 2030 to meet international climate change targets.
